Case Type   : 多节点写入
Case Name   : 在存储过程中执行INSERT/DELETE/UPDATE语句及DDL语句
Create At   : 2023/07/07
Owner       : opentestcase033
Description :
    1.修改enable_remote_execute参数值为on
    2.主机创建表和存储过程
    3.执行包含DDL语句的存储过程
    4.执行包含NSERT/DELETE/UPDATE语句的存储过程
    5.备机查看日志打印
    6.环境清理，恢复参数
Expect      :
    1.修改成功
    2.创建成功
    3.合理报错
    4.合理报错
    5.call语句识别为查询语句，在备机本地执行，不转发给主机
    6.成功
